    <p>I'm testing using sqlite. I have a different approach.</p> <p>I let NH create the connection, but store it in a static variable to pass it to subsequent sessions.</p> <p>When I begun to write the test framework, I had initialization code like this:</p> <pre><code>static IDbConnection staticSqliteConnection; if (staticSqlliteConnection == null) { sessionFactory.CreateSession().Connection; } </code></pre> <p>Then I had some issues and had too much test specific code in my production code (I prefer to have none). Hi-Lo id generators do also not work if you pass the connection to the session.</p> <p>Then I wrote a ConnectionProvider class looking like this:</p> <pre><code>public class SingleConnectionProvider : DriverConnectionProvider { private static IDbConnection staticConnection = null; public static void ResetConnection() { if (staticConnection == null) return; staticConnection.Dispose(); staticConnection = null; } public override IDbConnection GetConnection() { if (staticConnection == null) { staticConnection = base.GetConnection(); } if (staticConnection.State != ConnectionState.Open) { staticConnection.Open(); } return staticConnection; } protected override void Dispose(bool isDisposing) { ResetConnection(); } } </code></pre> <p>In the unit test cleanup method, you call <code>SingleConnectionProvider.ResetConnection()</code> which destroys the database for the next test.</p> <p>The whole thing is of course not fully thread safe. You can create as many sessions as you want, but you should avoid to create them concurrently.</p>

    1. COThank you for your solution, I'll try to implement a connection provider myself to solve the problem. Currently i've just a test creating a new session factory to test how Sqlite works. "Fluently.Configure()....BuildSessionFactory()" Which throws the above mentioned error message. In the long term I want to replace all mocked session factories with real factories based on an sqlite database.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
